TUXTLA GUTIERREZ, Mexico - Police on Tuesday detained 513 undocumented migrants from Latin America and Asia who were crammed into two trucks bound for the United States, prosecutors in southeast Mexico said.

The migrants, from Latin America, Japan, China, India and Nepal, "were traveling in inhuman conditions" in the southeastern state of Chiapas, near the Guatemalan border, the local attorney general's office said in a statement.
